See PR42773, the MIR function added in this patch causes trunk to fire an assertion, due to the repercussions of the LiveDebugValues spill restorer dropping fragment information.

This patch preserves that fragment information; it still loses extra expression information, however at the very least it doesn't cause llvm to crash.
